Revision: 2006 July 2007 FX35/FX45
DTC P1772 LOW COAST BRAKE SOLENOID VALVEPFP:31940
DescriptionNCS001G1
Low coast brake solenoid valve is turned ON or OFF by the TCM in response to signals sent from the PNP
switch, vehicle speed sensor and accelerator pedal position sensor (throttle position sensor). Gears will then
be shifted to the optimum position.
CONSULT-II Reference ValueNCS001G2
On Board Diagnosis LogicNCS001G3

This is an OBD-II self-diagnostic item.

Diagnostic trouble code “P1772 LC/B SOLENOID/CIRC” with CONSULT-II or 7th judgement flicker with-
out CONSULT-II is detected when TCM detects an improper voltage drop when it tries to operate the sole-
noid valve.
Possible CauseNCS001G4

Harness or connectors
(Solenoid circuit is open or shorted.)

Low coast brake solenoid valve
DTC Confirmation ProcedureNCS001G5
